yiph2, could you go to that black screen again and send me a Bug Report ? (HowTo => topic5-31732.php )
Another possibility is that the engine I'm using doesn't work with Intel IGP. I'll try to gather more info about that, and tomorrow, I'll try on my Mac, whose IGP is even older than yours (it's an Intel HD 5000).

Platform Mac OS X 10.12.6 with device Metal is not supported, no rendering will occur
So actually I could find the root of the issue : you need macOS 10.13 at least to run the current engine. Do you have the possibility to upgrade to it ?
